A Selection of our Projects

Automation, Robotics and Special Engineering in Detail

Automated nonwoven production line

Our production line brings together several nonwoven webs and joins them during continuous processing. Robotics, hot-melt adhesive application and automatic packaging complement the process.

How to request CNC contract manufacturing correctly: The checklist for a quick, reliable quote

Missing material specifications, unclear tolerances or conflicting CAD and drawing data can cause unnecessary delays to a CNC enquiry. Clarification takes time – and a quotation may end up being based entirely on assumptions. If you prepare your documentation thoroughly, you will receive a reliable quotation more quickly and minimise the need for subsequent changes.This checklist shows what information a CNC contract manufacturer typically requires for turned and milled parts, and how to structure your enquiry so that technical feasibility, quality, price and delivery date can be realistically assessed.
